Ecosystem service potentials, flows and demands-concepts for spatial localisation, indication and quantification

The high variety of ecosystem service categorisation systems, assessment frameworks, indicators,\udquantification methods and spatial localisation approaches allows scientists and decision makers to harness\udexperience, data, methods and tools. On the other hand, this variety of concepts and disagreements among\udscientists hamper an integration of ecosystem services into contemporary environmental management and\uddecision making. In this article, the current state of the art of ecosystem service science regarding spatial\udlocalisation, indication and quantification of multiple ecosystem service supply and demand is reviewed\udand discussed. Concepts and tables for regulating, provisioning and cultural ecosystem service definitions,\uddistinguishing between ecosystem service potential supply (stocks), flows (real supply) and demands as\udwell as related indicators for quantification are provided. Furthermore, spatial concepts of service providing\udunits, benefitting areas, spatial relations, rivalry, spatial and temporal scales are elaborated. Finally, matrices\udlinking CORINE land cover types to ecosystem service potentials, flows, demands and budget estimates are\udprovided. The matrices show that ecosystem service potentials of landscapes differ from flows, especially for\udprovisioning ecosystem services
